Günther's early sculptural works with video led him towards more journalistic oriented projects which he pursued in TV, print, and the art field. Based in New York, he played a crucial role in the evaluation and interpretation of satellite data gathered from political and military crisis zones; the results were distributed internationally through print media and TV news. The goal was to make military and ecological information, that was up to this point inaccessible, known to the public in order to have a direct impact on political processes. On an artistic level, the work with satellite data led to Günther's contribution to documenta 9 (1987), the installation K4 (C31) (Command Control Communication and Intelligence). In the same year, Günther received accreditation as a correspondent of the United Nations in NY.
